It's about a larger than usual Ragtag Bunch Of Misfits from alternate Universes, trying to find their way home while fighting working for a powerful interdimensional corporation which has used to keep them imprisoned them for reasons of its own.

At the end of Season 5, the producers decided not to renew the series for a sixth season, citing falling ratings and wanting to end on a high note. The last season wrapped most things up in a satisfying manner, yet left the door open for a possible continuation in some form at some time.

This series provides examples of

Action Girl: Jumapii. Although she was more of an Action Woman at 45. After her death, Hilde seems to be taking her place as the resident female badass.

Actual Pacifist: Ayela. She has gone as far as threaten Gao Chun with a gun, but it's uncertain if she'd ever have fired. Although her Character Development seems to be causing her to shed some of her principles.

Anyone Can Die: For a series that started out with very little violence, the body count sure has gone up since the end of Season 1. Now that they're even killing off main characters, who knows where it will end?

Black Dude Dies First: Whenever there's a battle, this trope seems to work. Jacques Artha in episode 9, Myo Obadele in episode 16, Matthau Bankole in episode 23. Of course there are a lot of black people in the series but still. Interestingly, Leonid has been responsible for all these deaths (ordering the attack on Jacques Artha, sending Myo Obadele to his death, and leading the group where Matthau Bankole was shot).

As a way of balancing the scales, in episode 27 a lot of really white dudes were killed first.

Bloodier And Gorier: Since getting out of Coventry, things have been getting more and more violent.

Chessmaster: Everything that happens, happens because Mizida has planned it to happen. Except maybe not managing to be on the first conveyor off Coventry, and seeing how season 3 is turning out so far, maybe even that.

Did Not Do The Research: Happens occasionally. Do not watch this for advice on how to survive a shipwreck or make bombs.

Disaster Scavengers: Schatzgräbers make their living in the ruined cities of Europe. Their timeline is not a happy place.

Disproportionate Retribution: Discover something Infinity would like to keep secret, no matter how minor? You get sterilization, a memory wipe and a ticket to a primitive tropical village for the rest of your life!

Eternal English: The characters have way too few difficulties with languages. Most of the time people several hundred years from each other speaking roughly the same language can understand each other well enough. Handwaved with the "Coventry pidgin" that everyone in the village will learn sooner or later.

Fantastic Racism: It is claimed that Homeliners see people from other timelines as inferior beings.

Failure Is The Only Option: Even though some Coventryans have actually found their way home in seasons 4 and 5, you can bet that none of the main characters are going to be so lucky. (Or can you?)

Reasonable Authority Figure: Tadena Aguina listens to Coventryans' complaints and actually manages to get Infinity to start negotiating with them instead of treating them like dangerous subhuman criminals.
